Founded in the 17th century. XIII to establish the mendicant order of Saint Francis (male order), legend attributes its foundation to the Saint himself. In 1271, the will of King Afonso III, the first document that references it, endowed the Convent with 50 pounds. Queen Isabel, wife of King Dinis, who most likely disembarked here in 1282, would favor the convent. It was rebuilt in the first half of the 1600s, from a medieval structure of which elements still survive. The mannerist facade dates from 1635. The entire convent underwent new interventions throughout the 17th century. In 1800, the facade of the church was renovated. In the 2nd half of the century. In the 19th century, in the convent area, after being subjected to readaptation works, the Military Hospital and later the Asylum Duque de Bragança were installed. The complex thus consists of a nucleus of church and convent, located on the left side of it. The longitudinally planned church, composed of a nave preceded by a galilee, with two protruding side chapels and a narrower choir, features internal covers with two differentiated slopes. The facades have stacked corners, with the front ones crowned by pinnacles. The main facade is finished with two slopes, dated to the 17th century, divided in the center by a perfect semicircular arch galilee (with the axial portal inside, with a counter-curved profile) and a rectilinear window. On the left side, there is a bell tower, with two registers, the upper one with a semicircular arch bell on each side. Among the various 18th-century altarpieces, the one in the chapel of Our Lady of the Conception stands out, where some rococo applications can already be seen. In this chapel, the scenographic painting of the ceiling is evident. The altarpiece of the main altar is neoclassical. Since August 26, 1985, part of the convent has been occupied by the District Archive of Bragança.
